Texas is home to 1,799 ZIP codes spanning 249 counties and over 1,100 cities, making it one of the most expansive postal networks in the United States. ZIP codes in Texas range from 73301 to 79980, with prefixes organized roughly by region — northern Texas around Dallas, the Gulf Coast around Houston, central Texas near Austin and San Antonio, and the vast stretches of West Texas and the panhandle. Harris County alone accounts for 145 ZIP codes, reflecting just how densely populated and geographically spread the Houston metro area has become. Whether you're mailing a letter to the Texas Hill Country or looking up a suburban neighborhood near Fort Worth, Texas ZIP codes offer a fascinating snapshot of the state's remarkable size and diversity.
Texas ZIP codes span a wide range of prefixes from 733 to 799, reflecting the state's enormous geographic footprint. The lower prefixes in the 733 and 75x ranges generally cover the northern and central regions including Dallas and its suburbs, while the 77x and 78x prefixes serve the Houston metro area and central Texas respectively. Far West Texas and the panhandle are covered by the 79x prefixes, illustrating how the postal system systematically organized delivery routes across one of the largest states in the country.
Harris County leads all Texas counties with 145 ZIP codes, a reflection of its status as home to Houston, the fourth-largest city in the United States, and its sprawling network of suburbs, unincorporated communities, and industrial zones.
